Just to help people make sense of some numbers and words...
85Hz to 20kHz... this means that these speakers cover the majority of the audible hearing range, that being said YOU WILL NOT hear what is known as "true bass" (20Hz to about 70Hz), but you shouldn't expect that from only a 4" driver, but what you do hear and what the "bass reflex" design increases, is the upper harmonics of the bass, which is fine up to a point, it's the frequencies which enable you to differentiate between instruments (i.e. what makes you know it's a double bass) you just don't have the fundamental frequencies, for that you need a subwoofer...
101.5dB SPL... this means these speakers get loud, like snowmobile / motorcycle loud. almost twice as loud as what will cause hearing loss (90dB, yes 10dB is twice as loud, it's a logarithmic scale)...
Now...
MSRP $229.99... THESE ARE NOT AUDIOPHILE... they might sound ok, but you will never get audiophile equipment for under $500, unless it's a capacitor or something... unfortunately in the audio world, you get what you pay for, and 230 bucks doesn't buy you much... I consider my sound system pretty good, but nowhere near audiophile level and I've spent thousands on it... Audiophile is an extremely overused marketing word, so just beware... If someone wanted a "reference" product for $230, I would recommend getting a nice pair of headphones (hears a hint, pretty much anything with out the word "beats" on it...).
That being said, for $90... I'd get them, why not, it's one hell of a deal...
